"God and his prophets have warned us for thousands of years to keep the sabbath day holy."
What about when, on a Sunday, fires start? When people are taken grievously ill or are in an accident? If people in a boat go overboard? What about law enforcement? Infiltrating a terrorist cell and/or intercepting their communications? Defending your country?
Are you suggesting that on a Sunday, the Fire Brigade, Paramedics & Hospital staff, Coast Guard, Police, CIA/NSA/Mossad/MI6/GCHQ et al, and Armed Forces should stop work immediately one second after 12 midnight on Saturday? Because if all those people in all those vital services were as Fundie (or were forced to be, as per your ilk's ultimate wish) followed your rules, you'd be fucked.
Just be glad there's Agnostics, Atheists, Humanists, or at least people whose religious belief isn't as extreme as yours, doing all those important jobs. Because otherwise, your country would be utterly fucked the first Sunday that came.
So a Superbowl is on a Sunday. Big freaking deal. Take it up with the NFL. And whichever TV station has the rights. And the American Football-loving population of the US as a whole. I'm sure they'll see things your way.
BTW, nice one Steelers, for winning a 6th Vince Lombardi Trophy. I was up till 3.15 AM watching it on BBC1, but it was worth the loss of sleep!
"All religions even believe in keeping one day a week holy"
O RLY? Ever asked a Jedi? (it's an officially & legally recognised religion here in the UK after the last Census). Even $cientologists would suggest otherwise. Contradicted, much?
